To all whom it may concern:

Be it known that I, HARRY H. Hoon, a citizen of the United States, residin at Chicago, in the county of Cook and tate of- Illinois, haveinvented certain new and useful Improvements' in Can-Filling Machinery, of which the following is a specification.

My mvention relates-'tannin machines and partcularl 'to' machines a apted for automatically lling cans or other receptacles with cdmminuated, granular or other finely divided materials such as food stuis. The' ob'ect of the invention is the rovision o-iilians actin upon-the materia supplied ereto in` bu k to fecd"'tlie same in a. substantially continuous manner to the re, cep. cles in an automatically aged amount an to fill the material into t e receptacles in'y measured quantities, thereafter applying aclosure vto the receptacle preliminary to the final sealing; the invention including,

means for automatically positioningl the empty receptacles and removing the same when filled.'

In order that the invention as hereinafter. more fully described and particularly claimed maybe clearly understood by those skilled in the art, I have in the accom 'anying drawings illustrated a 1preferre embodiment of the invention. n these draw- 4igure 1 is a side elevation of such 'a machine; i

Fig. 13 is a similar section on the line 13- 13 of Fig. 12, and

Fig. 14 is a fragmentary view of a transmission device.

In these drawings wherein similar reference numerals indicate corresponding arts throughout, 11 designates a hopper w ich, regardless of its sha e, constitutes a container for the materia to be operated upon. This hopper is in communication at its lower end with a tube 12, which in the embodiment shown, is deflected from a vertical position at 13 to a horizontal position at 14, the length of the tube is interrupted at 15 and is continued again at 16 as a tube section 17 of similar `fore. The ga at 18 is bridged by a sleeve"19 which is s idably mounted u on the tube sections-for a -pur pose to be ater described.

Within the lower cylindrical portion of the hopper 11 a plunger 20 is mounted for vertical reciprocation by means of a plunger rod 21 havin fixed upon its upper end' the cross head 2 and slidably mounted upon its medial ortion is another cross head 23. rod 21 and about the rod is arrange a helical spring 25 bearin upwardly against the lower face of the col ar 24 and seated below within the upper surface of the cross head 23. A pair o springs 26, 26 connects the ends of the two cross heads and connecting rods 27, 27 couple the outer ends of the cross head 23 with the crank pins 28 on the gears 29 which are driven by means of pnions 30, 30 upon the shaft 31 carrying the fly wheel 32 and driven by means of the sprocket 33 and chain 34 from the sprocket wheel 35 on the drive shaft 36.

The sleeve 19, above referred to, is provided with trunnions 37, 37 engaged 'by the arms 38 of a yoke having a stem 39 pivoted upon a crank pin' 40 which is adJustably .mounted in the slot 41 upon the side face of the cam 42. This cani is fixed upon a shaft 43 driven by means of the large gear 44 from the pinion 45 carried by the drive shaft 36.

Rigidly secured to und carried by the reciprocatory sleeve 19 is a cylindrical hous- A. set colar 24 is fixed u on the ing 46 the axis of which lies outsideV the sleeve 19. This housing incluses a disk 4T arranged concentrically Within the housing and provided ecccntrically theieofwith an 5 opening 48 of a diameter substantially corresponding to that of the interior of the sleeve. One wall of the opening is formed as aknife edge 49. The disk 47 is mounted upon an oscillatory shaft 50 in such manner as to slide longitudinally thereon b ut to be fixed against angular movement with reference thereto. This mounting maybe advantageously accomplished by providing the shaft 50 with an angular portion 51 and mounting the disk thereon as shown. The

oscillatory shaft 50 is provided at oneend with an arm 52 connected by a link 53 with an arm 54 ofV a rock shaft 55 having another armV 56 which travels in the groove 57 of the cam 42.

The operation of the machine as thus far described is asfollows: '1 he material, such for instance as corn beef,'is`supplied to *the hopper 11I and by the reciprocating plunger 20 is forced into and through the tube 12.

The actuation of the plunger '20 is a yielding one as the positivassn'iovementY 'ofthe cross head 23 "is transmitted by. meansofthe deriiins upon theresistf, `for instance, vthe 'halted in its'pas'sagetherethru hfthejresistance oifered by, thelsame to t e descent Y Y of the plunger 20 will cause the entire'` movement of the .cross headV 22;v to be taken up Y 40 by the springs 26, -thecross head`22 and the plunger 20 remaining stationary:r Y.

The material is' fed forward through the i Y section 14 of the tube 12iiit'o the chamber at 18. By means of. the cani 42 and its con- 45 nections with the oscillatory -shaft *50 the disk 47 is oscillated until the openin 48 is in re ister with the, interior of the s eeve which inc'loses fthe chamber 1.8, alud :the sleeve, housing and disk are thereupon moved to the right by means of the yoke 38,

the material within the chamber 18 presenting no obstacle to the movement of the diskby reason'of the opening 48 being in register -with said chamber. Vihen the 65 sleeve, housing and disk have reached 4a po- -sition to the extreme right, the disk is oscillated through the shaft 50 to bring the opening 48 out of register with the chamber 18, the knife edge 49 cutting through the mass of material within said chamber at thc point 15. The sleeve is thereupon moved to the left together with the housing and disk and as the opening in the disk is now out of register with'the chamber and an inipcrvious portion oi yshe disk extends across minnaar# .slot 75.

the chamber the material within the latter in front of the disk is forced to the left into the tube section 17. The length of feeding stroke'of the 'disk is readily controlled by means of the adjustable crank pin 40 by which the yoke stem is connected to the cam. Preferably the driving of the sleeve and the oscillation of the disk are timed to correspond to the actuation of the cross head 23, so that as the' disk moves to the left the material is fed forward behind said disk so as to maintain the chamber full. Each reciprocation ofthe sleeve and` disk serves to force'the material lin front of the disk forward. through the constricted bore of the tube 17 to the filling machine proper.

In the frame 58 is mounted a vertical main shaft 59 `carryinga crown gear 60 4in mesh with a bevel gear 61 upon a shaft 62 carrying a fly yvheel 63 and driven by a sprocket 64 and chain 65 from a sprocket 66 on the shaft 43.' -The mainv shaft 59'has keyed l f within each of which is mounted for vertical reciproctiona sleeve or pocket 69 adapted to rece'isfeithe cans V'IOfandpositiontfthe saine cally across-the ockets and seated the iian esj'of "the ta le'. fWithin each stada'r'd'ii74 mounted -upontliefbof i,

A drive pinion 80is fixed upon thfshaft 59 injmesh with the transmission pinion 81 which in turn' meshes with adriven pinion 82 fixed upon the shaft` 83 having upon its lower endlla crank disk 84 carryingan ecico iio

spring 92 snaps into engagement with the notches 93 to more accurately hold the table 67 during the intervals between the actuation of the Geneva gear, the purpose of this gear being to move the can holding ockets 69 forward step by step to receive t e cans and to position the saine beneath the filling tube, and then to discharge the same one by one from the machine.

Above the table 67 and the gears 80, 81 and 82 there is mounted upon the main shaft 59 a cylindrical mutilated gear 94 which is smooth throughout its periphery with the exception of a limited area and preferably, as shown, about one-sixth thereof being toothed at 95. Alongside the ear 94 is a cylinder 9G mounted upon the s aft 9T and having its eriphery divided into twelve divisions, eac alternate division being toothed at 98 to engage with the teeth 95 of the gear 94 while the intermediate alternate portions are concaved as shown at 99 to snugly fit the untoothed portion of the gear 94 in a complementary manner whereby during the time that the smooth portions of the two ears are in contact the cylinder 96 is locked against movement by vthe gear 94. The cylinder 96 is also held stationary at such times by means of a locking dog 100 formed as a toothed rack in mesh with the toothed segment 101 fixed upon a shaft 102 havin an arm 103,'connected by means of a lin -104 with the arm 105 of a slide 106 reciprocated Within the guide 107 by means of a groove 108 in the owcr face of the cam 109 engaging a roll 110 mounted upon said slide.

The cylinder 96 is provided with six equally spaced lon 'tudinally extending chambers 111, whic in succession are brought into register above with the discharge end 112 of the tube 113 connected to the feeding tube 17, and below into re ister with a vent pipe 114 guarded by a nelyperforated vent plate 115.

Upon the upper end of the main shaft 59 is mounted, as before stated, a cam 109. This cam is provided with a peripheral cam groove 116 within which travels a roller 117 mounted upon the head 118. This head has mounted upon its inner face a air of puii'ons 119, 119 which are in mesi exteriorly with two opposed stationary toothed* racks 120, 120, and interiorly in mesh with doubly racked bar 121 formed in its lower portion as a plunger 122, whereby the throw of the cani groove 1,16 is imparted in a. double degree to thc said plunger` 122, which plunger is in vertical alincinent with one of the chambers lll at the same time that another of the chambers is in register with the feeding tube. and while the cylinder 96 is sta tionary as before described.

Immediately above the cylinder 96 and contiguous to the upper face thereof is a cap feedin plate 123`within which and 'un mediately eneath the open bottom of theY cap magazine 124 operates a. slide 125 by which the caps 124l are transferred one by one from'the magazine to a position above that one of the chambers 111 which is in alinement with the plunger 122. This slide is intermittently actuated by means of the slide 106 previously described, an arm 126 of the same being connected to the lever 127 and the lever in turn being connected by the rod 128 with said slide, a spring 129 being interposed to form a yielding connection.

Upon the lower portion of each of the i pockets 69 are mounted pins 130 each carrying a pair of rollers 131 and 132. The rollers 131 are arran ed to travel upon a track comprising a pressed portion 133 and an elevatedl ortion` 134 connected by an incline 135. en traveling upon the depressed portion of the track the ockets occupy the position shown at the le hand in Fig. v6, their upper edges being flush with the top of the table. As the roller 131 travels up the-incline the pockets are elevated dually to correspond to the pitch of the incline until they reach the elevated portion 134 when theypccupy the position shown at the right hand in said Fig. 6. d

extend considerably" above the upper face of the disk so asto receive and position :accuratel the cans 70 beneath that chamber 111 which is in alinement with theplunger 122. At this time also the cam 79 operates to force the roller 131 upwardly against the standard 74 to lift the can and pressthe top of the sainel firmly against the plate 136 which is supported by the sprin 137 so as to eect a tight jointbetween t e can and the chamber. y

After passing this point the rollers 132 engage beneath the overhanging track `138 to positively lower the pocket 69 as it 'descends the incline on the opposite side so as to leave the filled can 70 in position to be wi d oi the table or removed in any suitab e manner.

Immediately after the pocket 69 reaches the .up er level 134 and is thus elevated above t e table 67 it is brought beneath the lower open end of a can chute 139 formed of the four an le bars 140, one at each corner, within whic i, the cans 7 0 fit. At the mouth of the chute are disposed a pair of inwardly inclined sprin clips 141 which serve to press against t e sides of the can and frictonallv retard the escent of the same. lmnic iately above the spring clips 141 are disposed a pair of blocks 142, 142 inwardly pressed by means of the bow spring 143, the ends of which are removably seated in the blocks, as shown at 144. The inner faces of these blocks downwardly converge as shown in Fig. 12. Upon the other two sides of the chute are arranged a pair of oppo il. w

sitely disposed sprin arms 145carried by a voke 146 upon a rod 147, the upper end of which is secured to the head 118 so that the spring arms 145 move in unison with the said head. The lower ends ofthe arms 145 are adapted to engage over the upper edge of :i can and force the same downwardly between the yielding blocks 142 and the clips 141 discharging the same from the open lower end of the chute into that pocket 69 which is positioned beneath the same, the spring arm 145 retreating upwardly to engage the next can which 1s Jfrictionally held by the blocks 142.

The operation of this. ortionof the machine is as follows: As t e material is supplied from the discharge end 112 of the feeding machine into that bne ofthe chambers 111 which is in re 'ster .therewith the chamber is completely. led under re'ssure fronrtlie reciprocating disk 47,;tl1e a1r being discharged `fronjifsaid eliamberg through. the
